The voracious scale insect ( Hemiberlesia rapax ) poses a major threat to kiwi production in France. This parasite, known to attack various fruit trees, inflicts significant damage by weakening plants and reducing fruit quality.

In this article, we explore the symptoms of infestation, best prevention practices, and effective control strategies. For affected growers, Kiwiverse, a wholesale supplier of kiwi plants, offers sustainable solutions to replenish your orchards and restart your production.

Symptoms of the Voracious Mealybug on Kiwis

On the leaves

• Sticky honeydew: This substance secreted by scale insects promotes sooty mold, a black, sooty mold.
• Premature yellowing: Leaves turn yellow, significantly weakening plants.
• Light spots: Mealybug bites leave visible marks on the leaves.

On fruits

• Reddish-purple or clear halos: These characteristic marks appear following mealybug bites.
• Deformation and cracking: The fruits lose their commercial value, becoming unfit for consumption or export.

On the twigs and branches

• Weakening of branches: The sap sucked by the scale insects deprives the branches of essential nutrients.
• Deformation of young shoots: This disrupts flowering and reduces production.
• Cracks and necrosis: In cases of significant infestation, branches may become necrotic, compromising the overall health of the plant.

Prevention: Best Practices to Limit Risks

Monitoring and early diagnosis

Regularly inspect leaves, branches, and fruit for early signs. Use double-sided tape to capture and identify larvae on your plants.

Optimal growing conditions

• Pruning: Prune regularly to improve air circulation and limit mealybug habitats.
• Moderation of nitrogen inputs: Excessive growth attracts pests.

Hygiene and maintenance

• Disinfect your tools: After each use to prevent spread.
• Remove and burn: Infested branches away from your orchards.

Favor natural predators

• Plant honey-producing flowers: Like phacelia to attract ladybugs and hoverflies.
• Install insect hotels: To encourage the presence of microscopic wasps, predators of scale insects.

Biological Control of the Voracious Mealybug

Use of natural predators

• Predatory ladybugs: Rodolia cardinalis and Exochomus quadripustulatus are particularly effective.
• Parasitoids: Insects such as Ericydnus sipylus parasitize the larvae, reducing scale insect populations.
• Carry out controlled releases of these auxiliaries to strengthen the fight.

Biopesticides

• Apply organic vegetable oils to smother mealybugs without affecting beneficial insects.
• Prepare a mixture of black soap and vegetable oil to spray directly on infested areas.

Creating a protective environment

• Maintain wild areas around plots to promote biodiversity.
• Grow host plants like nettle to attract natural helpers.

Conventional Control: Direct Solutions

Synthetic pesticides

• Specific products: Use approved insecticides such as Pyriproxyfen, targeting larvae at the right time.
• Optimal timing: Apply treatments during the plant dormancy period.
